1 Claim. 1

This application relates to improved methods for straightening rods. and more particularly to straightening metal rods.

One object of this invention is to provide an improved method by which a much higher output can be obtained than can be obtained by the construction made in accordance with Medart Patent No. 558,591, patented April 21. 1896.

Another object of this invention is to provide an improved method by which a higher output or straightened rods can be obtained.

With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art.

In the description and claim, the various parts and steps are identified by specific terms for convenience, but they are intended to be as generic in their application as the prior art will permit.

In the accompanying drawings forming part of the present disclosure, in which one way of carrying out the invention is shown for illustrative purposes:

Fig. 1 is a top plan view illustrating one way of carrying out the present invention;

Fig. 2 is a front elevation of Fig. 1;

Fig. 3 is a right end view of Fig. 2:

Fig. 4 is a sectional view on line 4-4 of Fig. 2; and

Fig. 5 is a sectional view on line 5-5 of Fig. 2.

Referring to the drawings, the rolls in and Ii could be respectively mounted in place of the rolls X and Y shown in the Medart Patent No. 558,591, with their longitudinal axes arranged in angularly crossed relation to one another. The roll II! is a convex roll having shafts I2 and 13 at its opposite ends for supporting it for rotation in suitable bearings (not shown), the shaft l3 having any suitable driving portion as 14 suitable to be drivably connected to any suitable driving-means (not shown) for rotating the roll l0. Similarly, the concave roll II has shafts l5 and it at its opposite ends for supporting it for rotation in suitable bearings (not shown), the shaft l8 having any suitable driving portion I! to be drivably connected to any suitable driving-means (not shown) for rotating the roll II.

Merely for convenience of reference in the claim, the term "median plane will be used. The median plane is defined or explained as that imaginary horizontal plane indicated by the line i8 (Figs. 2 and 3) which extends through the centers of both of the rolls I0 and II between and at equal distances from the ends of the two driv ing portions I4 and l'l'ot the two rolls.

An upper rod-guide l9 and a lower rod-guide 20 are mounted in adjustable position in any suitable way as, for example, in the previouslymentioned Medart patent. It will be noted that except for the entrance and exit portions of the guides l9 and 20, their respective opposite guidefaces 2| and 22 extend in approximately Parallel planes as most clearly illustrated in Figs. 2 and 3, and which planes are also parallel to the median plane l8.

The rods 23 and 24 which are to be straightened are fed in from the left end of Figs. 1, 2, 4 and 5, and owing to the arrangement of the rolls l0 and II and their directions of rotation as indicated by the arrows, the rods 23 and 24 are both rotated and straightened as they are fed toward the right. Thus, with regard to the rod 23, while it does not contact all portions oi! the rolls Ill and ii at any given instant, it is engaged between the convex surface 25 of the roll Ill and the concave surface 26 of the roll II and the guide-face or surface 2i oi the upper rod-guide I!) as it travels to the right and is straightened. And similarly, as the rod 24 travels to the right and is straightened, it engages or is in contact with the surfaces 25 and 26 respectively of the rolls I 0 and l i and the guideface 22 of the lower rod-guide 20.

In the claim, the rod-guides are stated as being located between the rolls and at opposite sides of the median plane of the rolls. The term at opposite sides does not have any significance as to horizontal or vertical, but merely as to relative relation as concerned with the median plane.

The invention may be carried out in other specific ways than those-herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claim are intended to be embraced therein.

I claim: 7

The process of simultaneously straightening two rods or the like including: passing two rods in the same general direction longitudinally into rod-straightening mechanism having a pair of straightening-rolls arranged adjacent but spaced apart from one another and rotating in the same direction of rotation about their respective longitudinal axes, which said axes are arranged in angularly crossed relation to one another, and
